The best way to stop the scheme is for nobody to take it, however that is very unlikely given the current employment opportunities elsewhere.
I'm not sure what the easyJet CC to do. They would end up backed into a corner and having to call for a strike ballot. How many of the current workforce do you think would walk out?
And yet it's all Balpa's and the eJ CC's fault for letting it happen.
This is purely the economics of supply and demand and something I would not don my donkey jacket for.
